DRAW-BAR AND SPRING.

SPECIFICATION forming part of Letters Patent No. 460,426, datedSeptember 29, 1891.

I Application filed May 4,1891. Serial No. 391,456. (No model.)

To all whom it may concern:

Be it known that I, FERDINAND E. OANDA, of New York city, in the countyand State of New York, have invented a new and Improved Draw-BarAttachment for Railroad- Cars, of which the following is aspecification, reference being had to the annexed drawings, forming apart thereof, in which Figure 1 is a perspective view of the draw barcase. Fig. 2 is a transverse section of the draw-bar and its case. Fig.3 is a transverse section of a modified form of the case, the sectionbeing taken through the springs. Fig. 4 is a longitudinal section. Fig.5 is a plan View with the cover removed. Fig. 6 is a plan view of amodified form, and Fig. 7 is a transverse section of the same.

Similar letters of reference indicate corresponding parts in all theviews.

The introduction of heavy-tonnage cars on the various railroads hascaused much difficulty in proportioning the draft-rigging to meet theincreased strain to which the same is subjected. Many of the devices inuse are objectionable in point of strength and stability and also in thematter of repairs and maintainance of the various elements constitutingthe draft-rigging-viz., the draft-timbers, the spring-case, thefollowers, the keys, the tail-bolt, (or equivalent-strap,) together withthe draw-bar, and other parts.

The object of my invention is to construct a spring-case having thegreatest possible strength and of such form as to secure the bestanchorage to the draft-timbers, while at the same time it is easilyaccessible for the renewal of the springs, followers, and other partswhich frequently break without the necessity of having to take the casedown to make such renewals or repairs.

To accomplish this, I construct the case A with the sides a extendingthe entire length of the case, the end stops b, which control the travelof the follower-plates, being an integral part of the case. Oppositesides of the case are provided with transverse ribs 0, which are gainedinto and bolted to the draft-timbers. To the sides and lugs of the caseis attached the bottom plate B, which is provided with recesses d nearopposite edges to receive the projections e on the lower edges of thesides of the case. In some cases I find it advantageous to make the sidepieces sepa rate and apply top and bottom plates, as shown in Fig. 3.The interlocking of the plates and side stops and the supportingvertical bolts impart to the case nearly as much strength as it wouldhave if constructed of one single piece of metal and without occasioningany undue strain. I prefer to make the top plate integral with the sideswhere the strap 0 is used, the lower plate only being separate, as shownin Fig. 1. In the'case are placed followers D D, having flanges f, whichengage the end stops Z), and between the inner flanged ends of thefollowers within the casing A are placed spiral springs g h undercompression. \Vhere the strap C is employed for taking the strain of thedraw-bar E, the followers are provided on their inner ends with bossesi, adapted to receive the ends of the inner spring h, and a bolt jpasses through the followers and the springs; but where the tail-boat Fis used and the strap is omitted the said bolt is of sufficient diameterto receive the inner spring, and the rear or inner end of the bolt isfurnished with a mortise, in which is inserted the key it, said keypassing between guides Z, projecting from the rear end of the rearfollower D. In this case the head of the tail-bolt is swiveled in thedrawbar, as shown in Fig. 6. To lighten the followers and at the sametime to increase their strength, they are corrugated in a longitudinaldirection, as indicated in cross-section, Fig. 2, the central portionsof the sides of the followers being thickened to increase theirstrength. This latter construction prevents the tail-bolt from turningwith the stem of the draw-bar, which ultimately cuts it out andoccasions serious expense for repairs. The key-guides also prevent thekeys from occupying other than a vertical position.

My improved casing permits of removing the parts of the draw-bar withoutthe necessity of disturbing the draft-timbers or other parts of thedraft-rigging, thereby saving expense in making repairs or alterations.This construction secures great strength in the parts connected with thedraft-rigging.

Having thus described my invention, I claim as new and desire to secureby Letters Paton?- 1. In a draw-bar attachment for railroad= cars, aspring-casing formed integrally with a single casting having a closedtop and an open bottom and constructed for attachment to thelongitudinal draft-timbers, substantially as herein shown and described.

2. In a draw-bar attachment for railroadcars, the combination,with thedraft-timbers, of a spring-casing permanently attached to the timbersand provided with a removable bottom plate extending the entire lengthof the casing and locked to the sides of the easing, substantially asspecified.

3. In a draw-bar attachment for railroadcars, a cored longitudinalcorrugated follower, substantially as specified.

4. In a draw-bar attachment for railroadcars, a cored longitudinalcorrugated follower having its sides thickened at or near the middlethereof, substantially as specified.

5. In a draw-bar attachment for railroadcars, the combination, with thetail-bolt, of means, substantially as described, for preventing theturning of the bolt, as set forth.

6. In a draw-bar attachment for railroadcars, the combination of amortised tail-bolt adapted to receive the pulling strain, and a followerfurnished with key-guides for preventing the tail-bolt from turning,substantially as specified.

7. In a draw-bar attachment for railroadcars, a spring-casing adapted tobe permanently attached to the draft-timbers and provided with one ormore removable plates thatlock with the sides of the casing,substantially as and for the purposes herein shown and described.
